Hey, hey, anyone out there struggling with acne or redness? Today, I'm going to introduce a serum. It's the serum from #Leporem, which is all the rage in Korea. LEPOREM Azelaic Acid 15% Premium AC Serum / 30ml / Serum @leporem_japan My skin tends to get rough with the change of seasons, and in my case, hot, sweaty weather always leads to rough skin. I've tried a lot of different products, but since I discovered this, it's become a real lifesaver. My favorite feature: It contains 15% azelaic acid and 10% niacinamide! The dual ingredients, azelaic acid* and niacinamide*, address acne and redness. Since I started using this, my skin feels soothed. The texture is amazing! It's thick, but it absorbs easily and isn't sticky! The refreshing texture is perfect for summer. Easy to use morning and night, it's become a daily essential skincare item. It also works to combat acne scars*! It's so exciting that it helps prevent and combat acne scars while supporting your skin. I wholeheartedly recommend it to anyone looking for clearer skin! This serum is available on Qoo10, and recently became available at Loft.

It was moisturizing and my skin felt soft and supple until the next morning! When I used it before applying makeup, it also helped my makeup go on well.
I previously used this brand's AC Cream Standard on specific areas of my skin when I had breakouts or severe skin irritation. This time, I tried the Premium version, which is perhaps the more advanced version of the serum. It contains 15% azelaic acid, but also plenty of other gorgeous beauty ingredients like niacinamide, ceramide, and tremella fuciformis extract, which I'm excited about, as it will likely help with dullness. The texture is light, like water, but it's moisturizing once absorbed. I think I could use just this one bottle except during the dry winter months. It's not sticky, so it's easy to use morning and night. With consistent daily use, my skin has become smoother and the roughness in my T-zone seems to have improved. I have sensitive skin, but I don't feel any particular stinging sensation, and I'm happy that I can use it morning and night. If you're interested in trying azelaic acid but aren't sure which one to choose, I highly recommend giving this a try!
It comes in a luxurious, sturdy bottle. Its capacity is 30mL. It comes in a dropper type, so you can use it hygienically without touching your skin directly, which is a nice feature. The serum has a comfortable texture that blends smoothly into your skin when you spread it. It moisturizes well without feeling sticky, and after use, your skin feels smooth and refined. It feels like my skin texture has been refined and smoothed. I'm also happy that my foundation goes on better♪ Just adding it to your daily skincare routine makes my skin look great, and it's my current favorite serum.
It's been a month since I started using it. I no longer experience any skin irritation or other issues. 3-4 drops is enough to cover the entire face, so it's a good value for the money. The serum is thicker than I expected.
